Error: The relative residual (3.6) is greater than the relative tolerance.

I would like to model a cylindrical beam undergoing tensile stress in the z direction in hoping to observe the resultant strain in the x and y directions. However, when I click study, i get this error: Error: The relative residual (3.6) is greater than the relative tolerance.
This error seems to run away when I applied a fixed constraint. however, applying fixed constraint is not what I want in my simulation.
The .jpg is what I wish to simulate. I also attached the comsol file if anyone wishes to correct me.
Thank you
Regards,
Jason Lee

I have the same problem and I don't know what to do as well.
Please update me when you find it.
Thanks

You should apply a force F at one end of the cylinder, but at the other end of the cylinder, where the reaction would be -F, you need to apply a displacement constraint. One way to do it is shown in the attached file. -DW
P.S. The system won't let me attach a file right now for some reason. I will try again later.
